The Board of Directors of
The BlackRock New York Investment Quality Municipal Trust Inc.:
In planning and performing our audit of the financial statements of
The BlackRock New York Investment Quality Municipal Trust Inc. for
the year ended October 31, 1994, we considered its internal control
structure, including procedures for safeguarding securities, in
order to determine our auditing procedures for the purpose of
expressing our opinion on the financial statements and to comply
with the requirements of Form N-SAR, not to provide assurance on
the internal control structure.
The management of The BlackRock New York Investment Quality
Municipal Trust Inc. is responsible for establishing and
maintaining an internal control structure. In fulfilling this
responsibility, estimates and judgments by management are required
to assess the expected benefits and related costs of internal
control structure policies and procedures. Two of the objectives
of an internal control structure are to provide management with a
reasonable, but not absolute, assurance that assets are safeguarded
against loss from unauthorized use or disposition and that
transactions are executed in accordance with management's
authorization and recorded properly to permit preparation of
financial statements in conformity with generally accepted
accounting principles.
Because of inherent limitations in any internal control structure,
errors or irregularities may occur and not be detected. Also,
projection of any evaluation of the structure to future periods is
subject to the risk that it may become inadequate because of
changes in conditions or that the effectiveness of the design and
operation may deteriorate.
Our consideration of the internal control structure would not
necessarily disclose all matters in the internal control structure
that might be material weaknesses under standards established by
the American Institute of Certified Public Accountants. A material
weakness is a condition in which the design or operations of the
specific internal control structure elements does not reduce to a
relatively low level risk that errors or irregularities in amounts
that would be material in relation to the financial statements
being audited may occur and not be detected within a timely period
by employees in the normal course of performing their assigned
functions. However, we noted no matters involving the internal
control structure, including procedures for safeguarding
securities, that we consider to be material weaknesses as defined
above as of October 31, 1994.
This report is intended solely for the information and use of
management, the Board of Directors and the Securities and Exchange
Commission.
